It addresses potential safety issues with engine mount hardware to prevent mechanical failure during flight. Failure to comply means the aircraft cannot legally fly."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-33-8-engine-mount-bolt-nut","history":"/api/acts/ad-beech-33-8-engine-mount-bolt-nut/history","analysis":"/api/acts/ad-beech-33-8-engine-mount-bolt-nut/analysis","conflicts":"/api/acts/ad-beech-33-8-engine-mount-bolt-nut/conflicts","importantCases":"/api/acts/ad-beech-33-8-engine-mount-bolt-nut/important-cases","documents":"/api/acts/ad-beech-33-8-engine-mount-bolt-nut/documents"}}
